Here is a spreadsheet gathering informations about almost all Samsung DAPs released since end of 2007. I did it because it was useful to me and I thought that may interest you too so I share it here

That was not very easy as only few information are available on the internet for some models but fortunately my "insider" status helped me a little
However, I still miss some data as you can see and I'm unsure about some others ( "?" ).
If you notice a mistake or if you can help to fill in the blank, please tell me

Interesting, didn't know the R0 uses a good old Austrian AMS codec, like the current Sansas. Makes the player even more likeable, besides being my favorite Samsung anyways. Also, makes me wonder why it is the only Samsung with that codec.

I wish I had that wisdom... I should have gotten a 32 or 64. 16 for me isn't enough anymore.

My first player was a 4GB Fuze with an 8GB card in it, and I remember telling TDS I'd never be able to fill it....and now, there are 14,187 songs in my library, although a decent amount of them are the "very rarely listened to" type.

I think I could fit everything I'd want to listen to on a 64 GB player, if I had to.....of course, I don't have one. Multiple players can be quite handy though.
